Fosi Audio V3 Mono

Product information "Fosi Audio V3 Mono"
Mono power amplifier for passive speakers


  • Ideal for subwoofers or minimalist setups 
  • Balanced XLR input RCA input with 25dB and 31db 
  • Texas Instruments TPA3255 amplifier chip 
  • A variety of input options RCA, XLR and TRS connectors 
  • Innovative design for heat dissipation 
  • Impressive output power 
  • Powerful sound in a compact size 
  • Automatic standby mode after 10 minutes 
  • 48V-5A power supply supplied 

The Fosi Audio V3 MONO is a compact, powerful yet affordable 1-way amplifier. 
Based on a TI TPA3255 amplifier chip, it can deliver up to 240W at 4Ω. 
In addition, this amplifier is equipped with a variety of audiophile-grade components, such as Japanese and German Elna and Wima capacitors respectively, or a duo of DIP8-mounted TI NE5532 OPAs that you can swap out if you want a specific sound colouration. 
In terms of connections, the Fosi Ausio V3 offers a balanced XLR/jack combo input, an RCA input and a speaker connection for the output. 

Noise and distortion-free amplification
The V3 mono amplifier benefits from PFFB technology, an advanced feedback design that significantly reduces distortion, improves linearity and increases efficiency. It also solves a structural problem of Class D amplification by eliminating the load dependency inherent in this technology. In addition, the aluminium housing isolates the power supply from the amplifier section, preventing crosstalk. 

A flexible amplifier
The V3 amplifier is designed to be integrated into various configurations. For example, you can easily switch between RCA and XLR inputs using the switch on the front. You can also adjust the gain of the RCA input between 25 dB and 31 dB. And if you want a different sound colour, you can swap the TI NE5532 OPAs via DIP8 mounting. 

A revised cooling system
To prevent overheating and thus ensure the longevity of the amplifier, Fosi Audio has developed an innovative ventilation system in addition to the traditional heat sink on the amplifier chip. The ventilation system is designed to prevent the ingress of dust without compromising cooling, ensuring impeccable sound quality combined with increased reliability.
